## What it is
A Ruby gem that enhances the standard Benchmark library with iterations-per-second (IPS) benchmarking. It automatically determines appropriate iteration counts for short code snippets and provides statistical comparisons between benchmarked blocks.

## Use cases
- benchmark ruby code snippets in iterations per second
- compare performance of two implementations
- measure how many times per second a block runs
- avoid guessing iteration counts when benchmarking
- generate statistical comparison reports for code benchmarks

## When to choose
- you need reliable Ruby micro-benchmarks with warmup and statistical error margins
- you want to compare the speed of alternative code implementations
- short code snippets make traditional time-based benchmarking unreliable

## When to avoid
- you need to benchmark full applications or long-running processes rather than snippets
- you are not working in Ruby
- you need profiling with memory allocation details rather than throughput

## Facets
- artifact type: library
- maturity: stable
- function: benchmarking, developer-tools
- domain: developer-tools, performance
- platform: ruby, cross-platform
- tags: benchmark, iterations-per-second, ruby-gem, performance-measurement, command-line
